Build Issue Integrating central NFC poller sample code into nRF5340 ADK headset app

[Larry_rad]

Hi.

I have integrated the NFC samples (nRF5340 DK) into the audio headset app (nRF5340 ADK), using SDK 2.5.2.  

For simplicity I've created two builds, a central version and a peripheral version.

The peripheral version was fairly straight forward to get to build. The central version has been giving some build issues.

I am getting 'undefined references' where the object files are being brought together, although seems to build into the objects ok.

The main items in question are nfc_poller_init/nfc_poller_process and log_set_tag.

The nfc_ functions are included in nfc_poller.h and nfc_poller.c, and these have been copied from the central_nfc_pairing sample with these two source files added to the source directory of the modified headset app in the same way they were for the central_nfc_pairing sample.  #include "nfc_poller.h" was added to the top of main.c and VS code picks up this link within the IDE and there are no squiggles or obvious issues.

log_set_tag is included in log_core.h, and is referenced in fw_app_info.c.  There is no #include for log_core.h at the top of fw_app_info.c, although this .c file is build generated, so it does not seem obvious that I can add the #include where I would expect to.

What can be causing these?

Thanks, Larry.

I am also having difficulty inserting the VS code terminal output into this ticketing system.  The OK button has no effect, if I paste this into the comment box I get an orange error box pop up.

Hi Laurence

'undefined reference' errors are usually caused by some missing Kconfig configurations. 

Did you make sure to copy the following configuration from the central_nfc_pairing sample into your own project configuration? 

#Condif NFC modules
CONFIG_NFC_NDEF=y
CONFIG_NFC_NDEF_RECORD=y
CONFIG_NFC_NDEF_TEXT_RECORD=y
CONFIG_NFC_NDEF_MSG=y
CONFIG_NFC_NDEF_PARSER=y
CONFIG_NFC_T2T_PARSER=y
CONFIG_NFC_T4T_HL_PROCEDURE=y
CONFIG_NFC_TNEP_POLLER=y
CONFIG_NFC_NDEF_LE_OOB_REC=y
CONFIG_NFC_NDEF_LE_OOB_REC_PARSER=y
CONFIG_NFC_NDEF_CH_MSG=y
CONFIG_NFC_TNEP_CH=y

CONFIG_POLL=y

Could you try the Insert -> Code feature? 

This is generally the best way to include logs, source code etc into a ticket. 

Best regards
